Personally, I think our language is rich enough to maintain the difference between racism and xenophobia, without confusing the two in some semi-literate way.
However, if we're going to say that the famine song is anti-Irish and racist, then you'll have to put The Fields of Athenry into the anti-British and racist category too.
You can't have it both ways. You can't mangle definitions and standards to favour one side.
